IMPROVEMENT IN OVSTER-DREDGE APPARATUS I Specification forming part of Letters Patent No. 177,02 dated May 2, 1876 application filed February 1, 1876. v I L To alt whom it may concern: 1

Be it known that we, GEORGE W. SLOAN and ELwooD GE'ISINGER, of Dividing Creek, in the county of Cumberland and State of low Jersey, have invented certain new and useful Improvements in Safe-WindingOyscr-Dredge Apparatus; and we do hereby de- *lare the following to be a full, clear, and exzt description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which Figure 1 is a perspective of our invention. The object of our invention is to provide means for preventing the sudden and dangerous recoil of the crank-arm in oyster-dredge winders, due to the line meeting a fast.

()ur invention consists, essentially, in the peculiar construction and combination of parts hereinafter described, whereby when a fast is met the crank-shaft will slide longitudinally, releasing its clutch from engagement with that of the driving-wheel, and thus prevent the recoil above mentioned.

Referring to the accompanying drawing, A A designate arbors or standards, designed to be fastened to the deck of the vessel, being held at their relative positions by cross-bars or rounds B B. O is the drum, sustained on the standards A, and provided with a fast. D is the crank-shaft, having a han-v dle or winch, d. E is a spur or driving wheel,- loose on the shaft D, and prevented from moving away from the adjacent standard A by a keeper, a. F is a clutclnfast on the shaft D,

and arranged to mesh or engage with the clutch e on the spur-wheel E. G is a sleeve, loosely encircling the shaft D, and held in contact with its adjacent standard A by a bracket, El, through which said shaft passes.

The end of this sleeve is made fast to or formed with a ratchet, I, with which a gravitypawl, k, engages. L is a pin, made fast in the shaft D, and passing through a beveled or spiral slot, 9, in the sleeve G.

The operation is as follows: Whenthe handle d is turnedto the right, in the-direction of the arrow, the line will be wound upon the drum 0, the clutches c and F then engaging, the wheels E and c gearing, and the shaft D and' sleeve Gr moving with said wheel E. Should a fast he met, the sudden recoil of the handle d will be prevented, as the strain,

2. In combination with clutch F, gearingE- c, and Windlass O, the sliding shaft 1), having a pin, L, and the loose encircling sleeve G, having the spiral or bevel slot 9, substantially as and for the purpose set forth. i

3. In combination with the shaft D, having pin L, and sleeve G, having slot 9, the bracket H, ratchet I, and pawl k, substantially as shown and described. x

4. The combination of standards A, drum 0,

pinion c, crank-shaft D, gear-wheel E,cluteh F e, sleeve Gr, bracket H, ratchet I, pawl k,

and pin L, the several parts being constructed and combined substantially as described.

In testimony that we claim the foregoing we have hereunto set our hands this 26th day of January, 1876. l
